Variant summary
Our verdict is Uncertain significance. Variant got 5 ACMG points: 7P and 2B. PM1PM2PM5PP2BP4_Moderate
The NM_001042492.3(NF1):c.5284G>A(p.Val1762Ile) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V1762D) has been classified as Likely pathogenic.

Neurofibromatosis, type 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 28, 2023 | This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 1741 of the NF1 protein (p.Val1741Ile). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with NF1-related conditions. ClinVar contains an entry for this variant (Variation ID: 404481). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt NF1 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
